I went to Game store in Acornhoek mall and I was treated very badly by the security guard and That also had my 3 years old baby girl injured. I was on my way out he called me from 2 meter away from the door that he wanted to search me, I was so embarrassed how he called me I felt like a *****, when I went back he then searched my bags, when he didn’t find anything he probably thought I stole he then started telling me that I can’t go out with a trolley 🛒… I told him to call the manager, he told me who am I to order him around. I asked him to let me go if he can’t call me the manager. When I was trying to leave he pulled the trolley harsh while my daughter was inside and it hit against the wall and got my daughter injured.
